5.6 PH and POH

Question 1

#1 What is the pH equation?
#2 What is the POH equation?
#3 What is the PKA equation?
#4 Other equations to know

Answer 1

#1 Ph= -log[h+]
#2 POH = -log [OH-]
#3 PKA = -logKa
#4 [H+] [OH-} = 1 x 10^-14
     pH + POH = 14

Question 2

Logs to memorize

Answer 2

10^-2   =   .01     =    Log(0.01)      =   -2
10^-1    =   .1        =    Log(0.1)        =   -1
10^0    =    1        =    Log(1)          =    0
10^1     =    10      =    Log(10)        =    1
10^2    =    100    =    Log(100)     =    2
10^3    =    1000  =    Log(1000)   =   3

Question 3

What will give us halves?

Answer 3

3.16 x 10^-1 = .5
3.16 x 10^-2 = 1.5
3.16 x 10^-3 = 2.5
3.16 x 10^-4 = 3.5
